Abstract (en)

[origin: US6479785B1] A device to place an incision into matter with a harmonious plasma cloud. A radiofrequency generator system produces pulsed or continuous electromagnetic waveform which is transmitted by an active transmitter incising electrode tip. This generated electromagnetic wave is utilized to initiate a plasma cloud with processes such as thermal ionization and a photoelectric effect which then trigger an Avalanche Effect for charged atomic particles at the surface of the active transmitter incising electrode tip. This electromagnetic wave is impedance matched, frequency matched, power matched and tuned to the plasma cloud in order to sustain and control a harmonious plasma cloud with reduced atomic particle turbulence and chaos. This harmonious plasma cloud forms a coating over the surface of the active transmitter electrode tip as well as acts to reduce the energy output needed from the power amplifier of our plasma cutting device. The electromagnetic wave is also used to produce a Pinch Effect to compress, contour, shape and control the harmonious plasma cloud. The electromagnetic wave is furthermore used to trap and contain the plasma cloud without the need of a solid matter containment vessel according to the Magnetic Bottle Effect of physics. The Tunnelling Effect of physical chemistry is utilized to focus and amplify the energy delivered to the harmonious plasma cloud while shielding matter surrounding the intended path of incision from potential electromagnetic radiation exposure. The invention is an efficient, effective, safe, clean and inexpensive device which can be used to place an incision in matter.
